Audio File Extensions
CD Audio (.cda) tracks are audio files that can be stored on CD media.
The .cda files are representations of CD audio tracks and do not contain the
actual
pulse code modulation (PCM) information. Cda files can be played only
from a CD-ROM. To test a .cda file, either try to play a different .cda file
from
your CD-ROM or try to play a .cda file from a different CD-ROM. Copied
from the CD-ROM to the hard disc it cannot be played. This is format used for
encoding
music on all commercial compact discs. If you buy a CD from a store,
the music on that CD is stored in CDA format.
The current standard for CD audio requires a sampling rate of 44.1 kHz
and a sample size of 16 bits (2 bytes per sample). As a result, you need to
store
2 x 44,100= 88,200 bytes of data every second to record in mono.
Recording in stereo would require twice that much storage. That extrapolates to
about
10 MB of data for every minute of stereo sound! It is for this reason
that compression schemes such as
MP3
are so important.
Unfortunately, your computer can't store files in CDA format, so you
still have to convert CDA files to another format to store on your hard disk.
